This is a tool for more easily creating a box shaped outline with four filleted corners. This is a common task in boat deck panel outlining work. This tool is accessed by default under the More Tools drop down on the Outlines toolbar. With just four mouse clicks you can create a rounded rectangle what would take 18 mouse clicks using Lines and Fillets. As well you get better definition of the parallel lines.
The steps to draw a rounded rectangle are as follows:
1. On a photo, click down on one edge of the rectangle close to one of the corners. Select a surface if needed.
2. Move the mouse to align the line with the edge being drawn and click down.
3. You will now see a prototype rounded rectangle being draw that follows the mouse. Move the mouse in X and Y to line up two edges (the opposite edge to the first edge, and the edge perpendicular at the side of the second point of the first edge). Click to define two edges.
4. You can now adjust the final edge. Move the mouse until the final edge lines up with photo edge and click down.
5. Optional: when the rectangle is finished it remains selected, this means you can use the Interactive fillet tool to adjust all four fillets at the same time.
Note 1: The four fillets that are created are defined by the current radius shown in the Radius: combobox on the Outline toolbar.
Note 2: If the fillet radius is too large for the current definition, the corners will be drawn with straight lines instead of arc fillets (this gives the rounded rectangle a strange X shape). Expand the sides until the fillet reappears or finish the drawing and adjust the fillet radii afterwards.
Note 3: You can start the rounded rectangle on any edge (the sides, the top, or the bottom).
